Professional Applications & Engineering Value
This M6 shoulder screw is engineered to address critical alignment and strength requirements in industrial applications. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, while the black oxide finish enhances surface durability and reduces galling. The precision shoulder with controlled diameter and length tolerances ensures accurate component positioning, minimizing misalignment in machinery, pivots, and rotating assemblies. With a coarse metric thread and Class 5g6g thread fit, it delivers reliable fastening under vibration, making it suitable for automotive, electronics, and heavy equipment where high tensile strength and repeatable performance are essential.
Specification Summary & Compliance
This shoulder screw features an M6x1mm coarse thread with Class 5g6g thread fit per metric standards, ensuring precise thread engagement. The shoulder diameter tolerance is -0.04 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm for accurate assembly. Manufactured from 18-8 stainless steel with a black oxide finish, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, supporting environmental and safety regulations in global industrial supply chains.
